To all whont @'15 may concern.'

Be it known that I, JULIEN TESSIER, a citizen of the Republic of France,residing in the city of Philadelphia, county of Philadelphia, and Stateof Pennsylvania, have invented certain Improvements in Film Cleaning andPolishing Mechanism, of which the following is a specification.

This invention is an improved machine for cleaning and polishing motionpicture films. Its primary object is to clean and polish such films in amore efiieient, con venient and expeditious manner than has heretoforeobtained.

It is characterized by its peculiar means for carrying the iilm,applying acleaning fluid thereto and rubbing the moistened film, thefilm being translated between reels by carrying mechanisms that keep itin proper tension under differential conditions, the fhuid beingautomatically supplied in the de- "sired manner and the brushes beingadjustable to and operable in various positions.

The nature of Amy improvements is fully set forth in the followingdescription and the accompanying drawings.

In the drawings, Figure 1 is a side eleva` tion of a machineembodying myinvention; Fig.- 2 is a. top plan view of the same; Fig. 3 is asectional view taken on the line 3MB of Fig. 1; Fig. 4 is a sectionalview taken on the line 4-4 of Fig. 1; Fig. 5 is an elevation of the sideopposite that shown in Fig. 1; Fig. 6, is a plan view of detached meansfor applying cleaning fiuid to the film; and Fig. 7 is -a part sectionalelevation of brush adjusting mechanism.

My improved machine, in the form thereof illustrated in the drawings,comprises the frame 1 having the reels 2 and 3 jour aled in the endsthereof. A film 4 is carried rom the reel 2 to the reel 3 under alroller 5 journaled in the frame and over a tension roller 6 journaledon the oscillatory arm 7 ful` crumed by means of the bearing 8 on theframe, the roller 6 pressing the film against the roller 5 due to theaction of the spring 9 which connects the arm with the frame.

The film is carried, from the bight of the rollers 5 and 6, over therolle-n10, which is journaled on the oscillatory arm 11 lulcrumed bymeans of the bearing 12 on the f1-ame, the arm being adjusted by a setscrew 13 rmovable through threaded sleeve 11 thereon and bearing againsta lug 1 on the frame. The film passes from the roller 10 in adjustablecontact with a roller '14, which applies a cleaning fluid thereto, andthence under the roller 15, over the roller 16, under the roller 17,over the roller 18 and around the differential tension roller 19 to thereel il, the roller 19 being carried by an oscillatory arm 20 whichrocks on the.

bearing 2l to compensate for the gradually increasingr rate of windingon the reel-8.

A brush 22 is journaled by the arbor 31 in thearm 23 which is adapted toswing on the arbor 24 concentric with the roller 14, the brush beingadapted to act against the film as it passes under the supporting roller15. A second brush 25 is journ-aled on the arm 26 which is adapted toswing on the arbor 27 concentric with the roller 17, this brush beingadapted to act on the lilin as it passes under the roller 15 and afterthe aeton thereon of the brush 22. Adjustable coiled springs 28 connectthe respective arms 23 and 2G with the frame, drawing the brushes 22 and25 toward the film.

A brush 29 is journaled on the arm 30 which is mounted on the arbor 31of. the brush 25 and supported by the Spring 30', the brush 29 acting incontact with the film as it jmsses under the supporting roller 17.

The brushes 22 lation to or moved. into and out of. contact with thefilm by the links 32 and 33 which connect the respective arms 23 and 26to a journaled disk 34, the disk being turned by the crank 35. An arm 36is connected with the disk 34 and .with a rod 37 having an enlarged endsection 38 movable through an aperture in a keeper 39, When the disk 34is turned t0 move the arms V23 and 26 apart, the rod 37. is movedoutwardly until the part 38 is beyond the keeper 39,When the rod willdrop down and. its inward movcment will be'prevented by the engagementof the forward shoulder of the part 38 with the keeper, whereby thebrushes 22 and 25 are held out of engagement with the film.

The'arm 30 is adjusted in relation to the film by the adjustment of thebrushes22 and 25, being provided with a roller 4:0 which engages astationary, cam 41 and and 25 are adjusted in re-' shifts the brush 29away from the film The mechanism is driven b a belt 43 which passes overa pulley 44 ]ournaled on the frame and having fixed thereto a pulley 45.A twisted belt 46 is driven by the pulley 45 and drives the pulley 47journaled on the frame and having the pulleys 48: and 49 fixed thereto.The pulley48 drives a belt 50 lwhich passes over a pulley 51 fixed tothe reel`3 by an arbor 52 journaled in the frame, whereby the reel 'isturned to wind the film thereon. .The pulley 49 drives a belt 53 whichpasses over a pulley 54 fixed onthe'arbor 55 journaled in the frame andcarrying the'roller 18. A pulley 24 fixed on the shaft 24 drives' a belt24 which passes over a pulley 15" which is fixed on the arbor, 15" ofthe roller 15. Pulleys 56 and 57, fixed to the pulley 44 and revolvedthereby, drive the respective belts 5S and 59 which pass over therespective-pulleys 60 and 61 fixed to the respective arbore 24 and 27which. are' journaled in the frame and carry the rollers 1'4 and 17.Pulleys 62 and 63 fixed to the respective pulleys 60 and 61 drive therespective belts 64 and 65 which pass over the respective pulleys 66vand 67 fixed to the arbors 31 and 31', the 4arbors being journaled inthe arms 23 and 26 and carryingthe brushes 22 and 25 which are driventhereby. A pulley 70 fixed on the arborl drives the belt 71, whichdrives the pulley 72 fixed to the arbor-73, the latter being journaledin the arm and driving the brush29.

t will 4be understood from the described connections of the drivingmechanism-that the brushes are positively driven in contact .tionprovided by with the 'film as the latter is drawn through the machineunder tension and compensathe swing permitted the hanging tension roller1 9.

The fluid, as alcohol, for cleaning the film, is contained in areceptacle 7 4, in which revolves a roller 75. adapted for carrying thefluid to the roller 14, whereby it is applied to the surface of the filmpreviously to the action thereon of the brushes,v the rollers 14 andt'i7 being covered with a proper fluid carrying material, such as felt.The roller 75 is journaled in arms 7 5l fixed on a shaft 751J which isjournaled in the brackets 74'* on the receptacle 74, the arms beingconnected by a cross rod 7 5. A. sprinfr 77, coiled on the rod 75, hasone end 7 in engagement with the receptacle 7 4 and the other end 7 7 lin engagement with the rod 75, whereby the roller 75 is held in thedesired frictionalengagement with the roller` 14. A ductor roller 76,whicli actsv arms 75l and 76"` to maintain the desiredpressure of theroller 76 on the roller 7 5.4

The receptacle 74 is provided with a regu- -by a conduit 81. The port 78leading to the passage 78 is controlled by a valve 82 which is adjustedin position by a float 83, the latter beineconnected'with the valve bythe levers Si having the stationary 'fulcrums 85.

It will be understood that the rise of fluid in the chamber 7 9 elevatesthe float 83 `which acts through the levers V84 to lower the valve 82and close'or partially close the port 78', thereby maintaining asubstantially constant level of the fluid in the receptacle 74. A

The fluid supply mechanism is carried on a plate 85vprovided with lugs86 in which is threaded a screw1 8? turned by a crank 88, whereby therelation of thc supply mechanism, and particularly the roller 75, totheroller 14 can be regulated.
